Answer:
x=0 x=9
Step-by-step explanation:
f(x) = x^3 - 9x^2
Set equal to zero to find the zeros
0= x^3 - 9x^2
Factor out x^2
0=x^2 (x-9)
Using the zero product property
0=x^2 0=x-9
x=0 x=9
There are no zeroes for an expression, only for equations.
Assuming equation to be
<span>−7x^2 − 91x − 280=0
-7(x^2+13x+40)=0
-7(x+8)(x+5)=0
by the zero product properties,
x+8=0 => x=-8
or
x+5=0 => x=-5</span>
It would be 2.6 x 104 for 26,500 in scientific notation.
Do you have a specific equation I can help you with. I can explain them better with a problem to look at?
